UAP-AC-Pro - Update Failed

We have approximately 120 new UAP-AC-Pro access points to configure and connect to our controller. They shipped with firmware 3.9.43.9166 and we are trying to update them to 4.0.21.9965. The update is failing when attempted. 

 

Here are the things tried:

-Update using the controller GUI

-Update through SSH (we tried with and without defaulting the AP)

-Update by copying the file via SCP

-Tried multiple new APs

-Tried loading an earlier firmware to 'step' it up to the latest (3.9.54 was the earliest tried)

 

"Update Failed" is the message shown on the controller.  We opened a support ticket, but we need these for a new building ASAP.  Any suggestions?

Re: UAP-AC-Pro - Update Failed

Hello @K_M_,

 

Try caching the firmware on the controller prior to the upgrade.

Settings > Maintenance > Firmware

 

How did you exactly upgrade via CLI?

Re: UAP-AC-Pro - Update Failed

Hi @AmazedMender16 

 

I followed the various methods described here:

https://help.ubnt.com/hc/en-us/articles/204910064-UniFi-Changing-the-Firmware-of-a-UniFi-Device

 

SSH Method:

1. Login

2. Run command:

upgrade https://dl.ubnt.com/path/to/upgrade-vX.Y.Z.bin

 

SCP Method:

1. Download the program WinSCP. This will allow an SCP session over SSH with a folder structure GUI. Use the SSH credentials to login into the UniFi Device. 

2. Download the bin file from our Downloads page.

3. Move the .bin file to the device's /tmp/ folder by dragging and dropping the file, rename the file to fwupdate.bin.

4. Connect via SSH and issue the following command to initiate a local upgrade.

syswrapper.sh upgrade2 &

 

 

I will try caching the firmware and get back to you shortly.


Thank you.

Caching seems to be working.  Strange that we never needed to do that before, but since it works I am happy.  Thanks for the tip!
